Natural gas stocks are rather low at about 14,000 Gwh, most unlikely to be an issue at this time of year unless some very exceptional event occurs.

I find it surprising though that the storage is not being refilled at the maximum flow rate. The wholesale price is much reduced to about 1.4 pence a Kwh.
Seems very odd not to fill whilst prices are low by the standards of recent years._________________"Installers and owners of emergency diesels must assume that they will have to run for a week or more"
